Pray for my glutes.

I have a slight obsession with celebrities — I mean, who doesn't? They're fascinating. And I've always been really fascinated with John Krasinski (JIM!!!), especially in light of his recent transformation from damn to damner.

Good job, John. You're an inspiration to us all.

But since the closest I ever get to an intense workout is a long hike with an Instagram after, I wanted to know what it was like to work out with an actual celebrity trainer.

So I turned to Jason Walsh, celebrity trainer and founder of Rise Nation for help.

He agreed to take me through a pretty average full-body workout and I agreed to try not to vomit on his shoes. (My butt hurt literally 5 seconds into this experience.)
